Hello,
this (longer) post deals with DirectoryIndex expansion,
Apache::PerlRun (Registry gives the same) and CGI's url('-relative' => 1)
method. The versions are 1.24, 2.68, 1.3.11 and 5.6.0+patches upto the
end of May. In the end, there is a proposed patch for CGI.pm, but as I'm
not sure if the behaviour is a bug or feature of mod_perl, I'm sending it
to [EMAIL PROTECTED] as well, for comments.
This config
<LocationMatch ^/testing/(index\.pl)?$>
SetHandler perl-script
PerlSetVar PerlRunOnce On
PerlSendHeader On
PerlHandler Apache::PerlRun
</LocationMatch>
and request for https://server/testing/ leads to redirect, where the
interesting values (printed via %ENV) are
PATH_INFO=/
PATH_TRANSLATED=/www/
REDIRECT_PATH_INFO=/
REDIRECT_PATH_TRANSLATED=/www/
REDIRECT_REQUEST_URI=/testing/
REDIRECT_SCRIPT_FILENAME=/www/testing
REDIRECT_SCRIPT_NAME=/testing
REDIRECT_URL=/testing/
REQUEST_URI=/testing/
SCRIPT_FILENAME=/www/testing/index.pl
SCRIPT_NAME=/testing/index.pl
This confuses CGI.pm, because $q->url('-relative' => 1) returns
'testing', not '' as would be expected.
If I change the config to be
<LocationMatch ^/testing/index\.pl$>
SetHandler perl-script
PerlSetVar PerlRunOnce On
PerlSendHeader On
PerlHandler Apache::PerlRun
</LocationMatch>
the redirect seems to be much less aggresive and the values are
REDIRECT_URL=/testing/
REQUEST_URI=/testing/
SCRIPT_FILENAME=/www/testing/index.pl
SCRIPT_NAME=/testing/index.pl
There is no PATH_INFO value here, as well. And the PATH_INFO being
set in the previous case is the cause of the trouble. I believe that
the following patch fixes the problem -- from '/testing/', even if
the path_info is '/', the relative address still needs to stay '',
not 'testing', otherwise '/testing/testing' is achieved in the link.
